Came across an interesting video about the Imagineering of DCA 1.0. Weird to see Kathy Mangum in the video talking about how guests found the park lacking lol. She goes on to talk about John Lasseter and a bug's land. She seems almost embarrassed in this interview in comparison to how she talks about Cars Land lol. The whole video is interesting, we sure have come a long way!
